[T]he Ares developer -- whose identity remains unknown -- has authored a free software development kit for the Trojan. The kit is intended for so-called "trustworthy developers," provided that they pay the Ares developer a licence fee when subsequent modules are sold to third parties.

In their release regarding the Trojan, G Data reported:

The developer of Ares even talked about the new malware in an underground forum. According to the author Ares is, "not focused on banking. Every copy of Ares is unique to its customer and it has the same banking capabilities as Zeus & SpyEye which can be added provided the customer wants it. I actually consider this more of a platform which is customized to each buyers liking.”
